Why doesn't Java support multiple inheritance?

In Java, a class cannot extend multiple classes. Therefore the following is illegal -

Example

public class extends Animal, Mammal{}

However, a class can implement one or more interfaces, which helps Java get rid of the impossibility of multiple inheritance.

The reason for this is to prevent ambiguity.

Consider a situation where class B extends class A and class C, and both classes A and C have the same method display().

Now the java compiler cannot decide which display method it should inherit. To prevent this, multiple inheritance is not allowed in java.
